CROSS REFERENCE TO RELATED APPLICATION(S)

This non-provisional application claims the benefit under 35 U.S.C. § 119(e) to Patent Application No. 106109541 filed in Taiwan on Mar. 22, 2017, which is hereby incorporated in its entirety by reference into the present application.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a control system, especially a smart light control system.

2. Description of the Prior Arts

Conventional lamps are difficult to adjust the number of light sources and the light emitting angle. For example, vehicle headlights are difficult to make such adjustments efficiently and as a result of that, the light beams from the headlights will shine directly into the eyes of the people in front of the vehicle, causing a temporary vision blackout and incurring the chances of accidents.

SUMMARY OF THE INVENTION

In view of the problems existing in the conventional lamps, the present invention provides a smart light control system which is capable of adaptively adjusting the brightness according to the brightness of the light source and the surrounding brightness, so as to improve the control efficiency and safety.

In order to achieve the above objectives, the technical solution adopted is to apply the aforementioned smart light control system which includes the following:

a light source device having a plurality of transparent parts and a plurality of sensors separately disposed beside a light source, wherein the sensors correspond to the transparent parts in terms of position, wherein a channel is formed between each of the sensors and its corresponding transparent part;

a controller connected to the sensors;

wherein the sensors transmit sensed signals to the controller based on brightness of light beams, and the controller adaptively adjusts the brightness of the light source according to the sensed signals.

Based on the structure in the aforementioned smart light control system, the surrounding light beams are allowed to get into the light source device through the transparent parts, and when light beams pass through the channels, based on the brightness of the light beams, the controller will adaptively adjust the brightness of the light source so as to achieve the purpose of improving the control efficiency and safety of the light source through the smart control.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following, with the drawings and the preferred embodiment of the present invention, further illustrates the technical means that the present invention adopts to achieve the intended purpose.

Regarding the first preferred embodiment of the present invention, with reference to FIG. 1, the smart light control system includes mainly a light source device 10 which further includes a plurality of transparent parts 11 and a plurality of sensors 12 which are disposed beside a light source, and each sensor 12 corresponds to a respective transparent part 11 in terms of position, wherein for light to pass through, a channel 13 is formed between each sensor and its corresponding transparent part, and a controller 14 is connected with the sensors 12. The sensors 12 send sensed signals to the controller 14 according to the brightness of light beams, and the brightness of the light source is adaptively adjusted by the controller 14.

By way of allowing the light source device 10 to pass the surrounding light beams through the transparent parts 11 to its internal channels 13, when the light beams pass through the channels 13 with their brightness sensed by the sensors 12, the sensors 12 will send the sensed signals to the controller 14 according to the brightness of the light beams, and the controller 14 will adaptively adjust the brightness of the light source based on the brightness of the light beams, so as to achieve the purpose of improving the control efficiency and safety of the light source through the smart control.

In this preferred embodiment, each sensor 12 may include a photosensitive resistor disposed in front of the light source. When the photosensitive resistor receives light beams, its resistance will increase when the brightness of the light beams get brighter, and as the resistance of the photosensitive resistor gets larger, the current flowing through the photosensitive resistor gets smaller, thus the controller 14 will lower the brightness of the light source, and vice versa: when the light beams get dimmer, the controller 14 will increase the brightness of the light source. The transparent parts 11 are disposed on a sidewall of the light source device 10. In this preferred embodiment, the transparent part 11 may include an opening, and a lens may further be disposed on the opening.

Regarding the second preferred embodiment of the present invention, with reference to FIG. 2, the technical contents of the second preferred embodiment are similar to those of the first preferred embodiment. However, in this embodiment, a transparent lamp casing 20 is further provided, and the lamp casing 20 has an internal receiving space therein accommodating the light source 10 and the controller 14. When the lamp casing 20 is in use (for example, the lamp casing is used as a headlight), the surrounding light beams or the light beams from the oncoming vehicle can pass through the lamp casing 20 and enter the transparent parts 11 and get sensed by the sensors 12 so as to allow the controller 14 to adaptively adjust the brightness of the light source according to brightness of the light beams.

Regarding the third preferred embodiment of the present invention, with reference to FIG. 3, the technical contents of the third preferred embodiment are similar to those of the previously mentioned embodiments; however, in this embodiment, a light concentrator 15 is further provided in the channels 13 which are formed between the transparent parts 11 and the sensors 12. The light concentrator 15 can effectively guide light beams so that the light beams can be focused on the most sensitive portion of the sensors 12, and that will help improve the precision of the smart light control system of this invention. In this embodiment, when the sensors are the aforesaid photosensitive resistors, as the central portions of the photosensitive resistors are more sensitive compared with the side portions of the photosensitive resistors, to avoid limitations due to the less sensitive portions, the light concentrator 15 will effectively guide most of the light beams to focus on the more sensitive portions of the photosensitive resistors.

In this preferred embodiment, the light concentrator 15 can be a light guide, a light collecting lens and a reflective cup.

Regarding the fourth preferred embodiment of the present invention, with reference to FIG. 4, the technical contents of the fourth preferred embodiment are similar to those of the previously mentioned embodiments; however, in this embodiment, the transparent parts 11 are disposed at different positions inside of the light source device 10. In this embodiment, the light source device 10 has a plurality of channels 13 in it, and the aforesaid transparent parts 11 and the sensors 12 are disposed separately, so as to receive light beams from all directions. For example, the transparent part 11 of a first channel is disposed at a first position, the transparent part 11 of a second channel is disposed at a second position, the transparent part 11 of a third channel is disposed at a third position, the transparent part 11 of a fourth channel is disposed at a fourth position, and so forth.
